1.2 Stud holder for drawn arc operation
The PH-3N, PH-3 and PK-3 stud welding guns can be equipped with a stud holder for
drawn arc operation when studs with a diameter of more than 6 mm are to be welded.
The stud holder is screwed on an adapter piece and can be installed into the PH-3
and PK-3 stud welding guns like the standard stud holder.
The stud holder must be screwed on the adapter piece tightly. When the screwed
connection is not tight enough, these parts could be damaged by scorching during the
welding process.
Drawn arc stud holders are especially suitable for operation with ceramic ferrules.
However, ensure a minimum stud length.

Ensure a minimum stud length when welding with ceramic ferrules:
Minimum stud length = Height of ceramic f 15 mm,
e.g. ceramic ferrule for MR10 stud = 10 mm high + 15 mm =
minimum stud length of 25 mm.
NOTE
Check to see if the stud holder is tightly screwed after installing it, otherwise there is a
risk of scorching during the welding process.
